Map of Achaea

The Regions of Ancient Greece were areas identified by the Ancient Greeks as geographical sub-divisions of the Hellenic world. These regions are identified in the works of ancient historians, geographers and in the legends and myths of the Ancient Greeks.

Achaea was the region in southern Thessaly and the northern coast of the Peloponnesus.

Those who marched against Troy were called Achaeans. The Achaeans came originally from Thessaly, in mainland Greece, and settled in Argos and Lacedaemon (southern Peloponnesus). In the 13th century the Principality of Achaea was founded in Greece after the Fourth Crusade.
